Panasonic(OTC:PCRF.Y) will be investing over $100 million in Tesla's (NASDAQ:TSLA) Gigafactory 1 plant in Nevada to boost battery production capacity by 10% to 39 gigawatt-hours (GWh) per year.

The factory is part of Tesla's critical infrastructure producing electric motors and battery packs for the Model 3 and Model Y electric vehicles. While both companies have wanted to boost production for some time, their relationship has at times been strained, though higher Tesla sales seems to have cleared that up.

According to Nikkei Asian Review, Panasonic will add one more production line to the 13 already operating at the factory, which currently produces 35 GWh of lithium-ion battery cells per year.

The two companies have wanted to boost production to as high as 54 GWh annually, but in April 2019, Panasonic said it first wanted to see if demand for electric vehicles warranted new investments.
